But the topic was about whether voltages were still being used to modulate 
the sound effects. The answer is that one may do it sometimes, but most 
digital-to-digital connections use a big stack of PCM protocols, such as 
MIDI, or RS232 or Ethernet/TCP/IP, the latter two in combination with 
ASCII-based or binary-based integer and float formats, etc. So in the end, 
the relation between voltage/timing and the effect is not the kind of 
thing that is obvious with an oscilloscope ;)

In the set of all possible frequencies of photon particles, are things 
discrete ? I've never read that ever.

The interference in the sensor, the cable and the ADC, and the 
irregularities in the construction of the sensor and the ADC, will 
completely submerge any quantum effects that you'd like to perceive. Is 
that right ?
